INTERNAL BATTERY
The X5105 comes with a built-in 3800-mAh battery pack. When no external power source
is connected to the radio, the battery supplies power by default. When an external source
is connected, power-management circuitry switches to it automatically.
Charging Procedure:
1. In the menu, select the [CHG] option, then select CHG ON.
2. Adjust the external power source to between 13.5V-14.0V and connect it to the
X5105 power supply input. Charging will start automatically. You must apply at least
13.5 volts to ensure proper charger operation.
3. The maximum charge time for a fully depleted battery is about 10 hours. When the
battery is fully charged, power-management circuitry terminates the charging cycle.
When the radio’s battery power is nearly depleted, the battery symbol located at the
upper right corner of the display screen will appear “empty”: At this point, you
should switch to an external supply or recharge the battery. Note that during the recharge
cycle, it is normal for the X5105 case to become warm.
Normally, the life span for the internal battery is around 3 years. When there is a
significant drop in capacity or a charging failure, you may contact your dealer to obtain a
replacement. Replacement costs beyond the warranty period are not covered.
IMPORTANT OPERATING WARNING: When your X5105 is connected to an external
power source and the radio is in transmit mode, DO NOT disconnect the power supply.
Doing so can damage the radio’s power management IC chip.
IMPORTANT BATTERY WARNING: In the unlikely event the case of the X5015 becomes
extremely hot around the battery area, turn off power immediately and remove the
radio to a safe well-ventilated area! After confirming the safety of the situation, please
contact us for proper handling information.
